UNITED STATES AUGUST EINER, OF NEW YORK, :N1 Y.

ELECTRIC PRESSURE GENERATOR.

Application led May 10, 1924. Serial No. 712,239.

This invention relates to a novel power generating system employing certain kinds of fluid media, other than water, which are possesed of characteristics that render them 5 particularly serviceable for employment in a closed power circuit, together with the use of electrical resistance heating means under such regulated cont-rol that the temperature of the fluid medium may be raised to and maintained at the point or degree suitable for desirably expanding the fluid medium.

Essentially my invention, in one form thereof, comprehends the employment of a fluid medium which is relatively' a non-conductor of electricity, for the reason that the resistance conductors are preferably exposed or partially exposed to direct contact with the fluid medium as the means of attaining the greatest heating efliciency for the amount ot' current consumed.

Furthermore, my invention includes the provision of a large number of resistance conductors within the generator, so arranged that they cannot enter into short crcuiting relation, but serving lto supply heat at numerous points throughout the body of the fluid medium. By equi-spacing of the resistance conductors in the body of fluid medium the temperature thereof is raised evenly throughout, resulting in the production of a uniform cycle, as the expanded medium passes off to perform work, is condensed and returned to the generator.

In another form of my invention, where it may be desirable to have the electrical heating units removable from the generator while in service, for repair and replacement purposes, I provide a pressure containing casing, in the form of a. boiler and tit therein one or a number of tubes, whose open ends are exposed outside the casing, so that a resistance conductor, suitably insulated, may be removably inserted within the tubes to supply the heat necessary in creating pressure. f

Other features and advantages of my invcntion will hereinafter appear.

In the drawing:

Figure 1 is a vertical, sectional View of a generator embodying my improvements.

Fig. 2 is a section on the line 2-2 of Fig. 1.

Fig. 3 is a diagrammatic elevation of a power plant including my improved generatin means.

Fig. 4 is a side sectional elevation of a va boiler' which contains as a pressure medium a liquid that is relatively a non-conductor of electricity, such for instance as ycarbon tetrachloride, acetylene bichloride or other ofi the acetylene compounds, carbon perf chloride, or equivalent liquids.

Liquid pressure media such as the foregoing are employed by .me for genera-ting power mainly because they are cxpansible at relatively low temperatures, are non-inammable, and are relatively non-conductors of electricity, so that electrical resistance conductors, without insulation, can be placed within the boiler in direct contact with the liquid therein, without the occurrence ot' short circuiting through the liquid medium.

I am aware that other liquids, expansible at higher temperatures, also relatively nonconductors of electricity', are available for use as pressure media in my improved generator.

In heating with electrical resistors efficiency is achieved by exposing a bare resistor directly to the substance to be'heated, since the intensity of the heat delivered by the resistanceconductor is diminished when delivered through insulation of any character, and therefore the essence of my invent-ion, in this form thereof, consists in the employment of a` relatively non-conductive liquid expansion medium, and in applying direct to such medium the bare surface of the resistor.

vAnothercharacteristic feature of the liq4 uid pressure media referred to as employed by me is that no chemical react-ion occurs between them and metallic or other resistors, whose service life is thereby not diminished by corrosion or deterioration oit any kind, nor are the resultant vapors poisonous or otherwise harmful.

Efficiency in vapor generation is further served by placing a plurality of resistors in 110 ril() close, spaced relation, to provide a maximum of heating surface, and if the resistors be will he insulliieient to set up any appreciable 'rent through the liquid 111edi11111.
